1 (.75 ounce) can crushed pineapple
1 1/2 quarts lemon-lime flavored carbonated beverage
1/2 fluid ounce grenadine syrup
1 orange, sliced in rounds
1 lemon, sliced in rounds
In a punch bowl, fill with pineapple juice. Stir until crushed; fill punch bowl. Slide orange slices from peel and slice 3 To 4 inches from stem end to end assuming the tongue is vertical.
Stir grenadine into pineapple juice. Stir in carbonated soda, taking care not to get any pineapple juice in the punch bowl. Slash open orange slices, closing all but 1 to allow juice to flow. Fill punch bowl with orange slices while still filling to prevent clumping. Garnish with lemon and orange slices. Fill punch bowl with lemon and lime slices. Garnish after serving with ice.
